Commenting on Revelation 1:9-20

Geneva Bible Notes Reformed

The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches. (14) That is, the thing which was mystical signified by the particulars of the vision before going. (l) By angels he means the ministers of the Church.

Jamieson-Fausset-Brown Reformed

in--Greek, "upon My right hand." the mystery . . . candlesticks--in apposition to, and explaining, "the things which thou hast seen," governed by "Write." Mystery signifies the hidden truth, veiled under this symbol, and now revealed; its correlative is revelation. Stars symbolize lordship (Num 24:17; compare Dan 12:3, of faithful teachers; Rev 8:10; Rev 12:4; Jde 1:13).
